+*				of TCL_TOKEN_VARIABLE tokens.
+* TCL_TOKEN_SIMPLE_WORD -	This token is just like TCL_TOKEN_WORD except
+*				that the word is guaranteed to consist of a
+*				single TCL_TOKEN_TEXT sub-token.
+* TCL_TOKEN_TEXT -		The token describes a range of literal text
+*				that is part of a word. NumComponents is
+*				always 0.
+* TCL_TOKEN_BS -		The token describes a backslash sequence that
+*				must be collapsed. NumComponents is always 0.
+* TCL_TOKEN_COMMAND -		The token describes a command whose result
+*				must be substituted into the word. The token
+*				includes the enclosing brackets. NumComponents
+*				is always 0.
+* TCL_TOKEN_VARIABLE -		The token describes a variable substitution,
+*				including the dollar sign, variable name, and
+*				array index (if there is one) up through the
+*				right parentheses. NumComponents tells how
+*				many additional tokens follow to represent the
+*				variable name. The first token will be a
+*				TCL_TOKEN_TEXT token that describes the
+*				variable name. If the variable is an array
+*				reference then there will be one or more
+*				additional tokens, of type TCL_TOKEN_TEXT,
+*				TCL_TOKEN_BS, TCL_TOKEN_COMMAND, and
+*				TCL_TOKEN_VARIABLE, that describe the array
+*				index; numComponents counts the total number
+*				of nested tokens that make up the variable
+*				reference, including sub-tokens of
+*				TCL_TOKEN_VARIABLE tokens.
+* TCL_TOKEN_SUB_EXPR -		The token describes one subexpression of an
+*				expression, from the first non-blank character
+*				of the subexpression up to but not including
+*				the space, brace, or bracket that terminates
+*				the subexpression. NumComponents counts the
+*				total number of following subtokens that make
+*				up the subexpression; this includes all
+*				subtokens for any nested TCL_TOKEN_SUB_EXPR
+*				tokens. For example, a numeric value used as a
+*				primitive operand is described by a
+*				TCL_TOKEN_SUB_EXPR token followed by a
+*				TCL_TOKEN_TEXT token. A binary subexpression
+*				is described by a TCL_TOKEN_SUB_EXPR token
+*				followed by the TCL_TOKEN_OPERATOR token for
+*				the operator, then TCL_TOKEN_SUB_EXPR tokens
+*				for the left then the right operands.
+* TCL_TOKEN_OPERATOR -		The token describes one expression operator.
+*				An operator might be the name of a math
+*				function such as "abs". A TCL_TOKEN_OPERATOR
+*				token is always preceded by one
+*				TCL_TOKEN_SUB_EXPR token for the operator's
+*				subexpression, and is followed by zero or more
+*				TCL_TOKEN_SUB_EXPR tokens for the operator's
+*				operands. NumComponents is always 0.
+* TCL_TOKEN_EXPAND_WORD -	This token is just like TCL_TOKEN_WORD except
+*				that it marks a word that began with the
+*				literal character prefix "{*}". This word is
+*				marked to be expanded - that is, broken into
+*				words after substitution is complete.
